The Importance of Earth's Magnetic Field:While we may not notice it in our everyday life, the Earth is constantly surrounded by a magnetic field it creates. The Earth's magnetic field is what protects us from the solar wind given off by the Sun. Without this magnetic field the solar win...

The Earth is a giant magnet, with a north and a south pole just like any magnet you’ve ever played with. But the Earth’s magnetic field plays a vital role: It helps to prevent powerful solar particles from destroying us. Scientists think the magnetic field comes from something called th...
Some animals can sense the earth's magnetic field (磁场),while humans can't.This magnetic field guides a certain kind of fish when they swim a long way to a place and then back.How can this kind of fish do that?It is still a mystery.Scientists have no good an...
Earth is no exception, right?Male student: Right.Professor: Okay, keep in mind that solar wind is electrically charged, which means that it interacts with the magnetic field as electromagnetic theory tells us. Okay, how does it interact? Earth, magnetic field deflects most the solar wind, ...
Migratory birds traveling long distances at constant intervals have long been considered to be able to sense the Earth’s magnetic field. Sometimes, these birds fly thousands of miles towards the target direction. Until recently, it has not been known what kind of mechanism allows to birds to ...
Flowers are abundant everywhere. It was also known as the Full Corn Planting Moon or the Milk Moon. June 11: Full Strawberry Moon The full moon of June, also known as the Strawberry Moon, looms above Earth's horizon in this photo taken by an astronaut at the International Space Station....
Each line of longitude begins and ends at the Earth's poles and represents direct north and south travel. Compasses, on the other hand, direct you to magnetic north, a point in the arctic regions of Canada that continually shifts location based on the activity of Earth's magnetic fields. ...
Thenorthern lightsare caused by electrically charged particles from the sun smashing into Earth's magnetic field. This "solar wind" is funneled down to the magnetic poles of the Northern and Southern Hemispheres, creating green, red, and blue swaths that swivel and shape-shiftover the Arctic Ci...
